Okay, I tested with clean installed oneiric Beta2, problem still exists. The suspect is pkgbinarymangler::pkgstripfiles(::optipng). pkgbinarymangler kicked at build-process in only archive-build[1]. We built at PPA/private pbuilder, pkgstripfiles does not kicked[2] and that works fine.

Collateral evidence:
When you install good fontforge packegs from my PPA[3], exec below command...problem reproduced! Breaker is optipng (of cource, fontforges PNG reader is still suspicous, and we need workaround).
  <<<WARNING: Before exec, please backup *png files>>>
 $ cd /usr/share/fontforge/pixmaps/
 $ sudo optipng -o4 -preserve *png

So, we have to one-more-rebuild with NO_PNG_PKG_MANGLE for good fontforge packages.

# But, we are in FinalFreeze :(
